<span>Halflife is the time needed for a radioactive molecule to decay half of its current mass. If t is the time elapsed, the formula for the halflife would be:
final mass= original mass * </span>\frac{1}{2} ^{\frac{t}{halflife}
<span>
If you put the information of the problem into the formula, the equation will be:
</span>final mass= original mass * \frac{1}{2} ^{\frac{t}{halflife}
final mass= 800g * \frac{1}{2} ^{\frac{t}{16 min}
